Bios blocked

Hello. I have a problem with a Dell Inspiron 3000 laptop. Please, is there anyone who can help me? I forgot my bios password, because I haven't entered my laptop for a long time and now I can't enter at all. Service Tag: 1MNB982 and EXPRESS SERVICE CODE: 3546194546 Thank you in advance. A beautiful day! Respectfully!

I did not say that I tried to remove the battery from the motherboard, more I did not want to try, that is the phase with jumpers, because I do not understand and I did not want to risk burning the plate.
